noncircular
|non-cir-cu-lar|
🇺🇸
/nɑnˈsɝkjələr/
🇬🇧
/nɒnˈsɜːkjʊlə/
not circular (shape, logic, or loop)
Etymology
'noncircular' is formed by combining the prefix 'non-' (from Latin 'non', meaning 'not') with the adjective 'circular' (from Latin 'circularis', from 'circulus', meaning 'circle'). 「noncircular」は接頭辞「non-」(ラテン語 'non':否定)と形容詞「circular」(ラテン語 'circularis'、さらに 'circulus':「円」)が結合してできた語である。
'circular' entered English via Old French and Middle English from Latin 'circulus' ('circle'), later forming the adjective 'circular'; the productive prefix 'non-' has been used in English since Middle English, ultimately from Latin 'non'. 「circular」はラテン語 'circulus'(「円」)が古フランス語・中英語を経て英語に入り、形容詞 'circular' を形成した。接頭辞 'non-' は中英語以来英語で使われ、語源はラテン語 'non' に遡る。
Originally the components meant 'not' + 'of or relating to a circle'; over time the compound has been used both for literal shape ('not circular') and extended senses such as 'not circular in reasoning' or 'not forming a loop'. 当初は「否定」+「円に関する」を意味していたが、時間とともに文字どおりの形(「円形でない」)だけでなく「論理的に循環していない」「ループを形成しない」といった拡張的な意味でも用いられるようになった。
